METAL COMPLEX, LIGHT EMITTING ELEMENT, AND DISPLAY DEVICE
The present invention provides a metal complex which contains a cation that is represented by [(MII)2(MI)2(LC)2(LB)4]2+ (wherein MII represents PtII or PdII
MI represents H+, AuI, AgI, CuI, HgI, TlI or PbI
and LC and LB each represents a ligand). This metal complex is useful as a light emitting material for an organic EL device.
